OPERATION IN SALT WATER AREAS
When the centrifugal pump unit is operated near salt water, the salt air will quickly cause corrosion of unpainted surfaces.
a.
Coat machined surfaces with oil.
b.
Use fresh water to wash off any salt water that comes in contact with the equipment.
c.
Contact organizational maintenance to remove any rust or corrosion, and cover the exposed surfaces with

FORDING
If the centrifugal pump unit must be towed through deep water, prepare the equipment for movement according to
paragraph 2-7, then continue with the following steps.
Do not submerge the centrifugal pump unit to a depth that would wet the starter motor.
a.
Secure the dust cap in place on the pump priming port.
b.
Openings that will permit direct entry of water shall be sealed with pressure-sensitive tape conforming to
PPP-T-60, Type IV. Large openings shall be bridged with waterproof barrier material conforming to PPP-B-1055. The
edges of the barrier material shall be secured to adjacent surfaces with tape specified above.
c.
After fording, rinse the centrifugal pump unit with clean water, and remove debris from the unit. If the unit is
towed through salt water, rinse the unit with clean water containing a mild detergent, and remove debris from the unit.
